Abstract
According to an embodiment, a structured document management device includes a parser; a constraint acquiring unit; and a parse tree rewriting unit. The structured document receiving unit is configured to receive an input of a structured document having a layered logical structure. The parser is configured to parse the syntax of received query data to acquire a parse tree in which the query data is decomposed so as to meet a static single assignment form which is defined such that each variable is assigned exactly once. The constraint acquiring unit is configured to acquire a hierarchical condition that the variables of the parse tree need to meet and constraints that include conditions for values of the respective variables. The parse tree rewriting unit is configured to rewrite the query data in such a form that the structured document is refinable by the constraints.
